VALVE.

SPECIFICATION forming part of Letters Patent No. 592,986, dated November2, 1897. Application filed April 27, 1897. fierial No. 634,129. (Nomodel.)

To ctZZ whom it may concern:

Be it known that I, GEORGE W. Fon'rnnn, a citizen of the United States,residing at Moweaqua, in the county of Shelby and State of Illinois,have inventeda new and useful Valve, of which the following is aspecification.

My invention relates to valves, and particularly to check-valves, andhas for its objectto to provide a valve of which the parts may bereadily disassembled and wherein lateral access is given to thevalve-seat, whereby the members thereof may be reached for cleanin gwithout disconnecting the casing from the pipe or conveyer sections ofwhich it forms a union.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a longitudinal sectional view of a valveconstructed in accordance with my invention. Fig. 2 is atrans- 2 5 versesectional. view. Fig. 3 is a detail view in perspective of the guide.Fig. at is a detail view of thevalve-seat detached.

Similar numerals of reference indicate corresponding partsin all thefigures of the d raw- 0 ings.

1 designates a casing provided with terminal male and female threads forattachment to contiguous portions of pipe or conveyer sections and alsoprovided with a lateral 5 opening 2, which is closed by a removablecap-nut 3. In one end of the casing is formed a shouldered valve-seatrest at, in which is re movably fitted a valve-seat 5, having acircumferential enlargement or shoulder 6 to engage the shoulder of therest and fitting snugly in the cylindrical bore of the casing beyond theshoulder of the rest to avoid the necessity of employing fasteningdevices. The

valve-disk 7 is provided with a winged guide 8 to fit in the bore of thevalve-seat and also with an axial cross-sectionally-round extension 9 tofit in a guide-opening 10 in a removable guide-arm 11, said guide-armbeing provided with a segmentally-rounded blade 12,

which fits peripherally in a guide-groove 13, formed transversely in thecasing opposite to the lateral opening 2 and provided at the oppositeend with a winged arm lat to fit in a cross-sectionally-round socket 15in the capnut.

It will be seen that the socket of the capnut supports one end of theguide-arm, while the guide-groove in the wall of the casing supports theother end of said arm, whereby the valve-disk is free to movesufficiently to unseat, While at the same time it is guided both aboveand below its plane, respectively, by the winged guide and theextension. Furthermore, it is obvious that byremoving the cap-nut theguide-arm may be displaced, thus releasing the valve-disk and allowingit, with the valveseat, to be displaced for cleaning, regrinding, orrepairing in other respects.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my intention, what I claim is-- 1. The combination of avalve-casing having a lateral outlet provided with a removable closure,a valve-disk seated in the casing and provided with an axial extension,a guidearm having a guide-opening to receive said extension and with aflat blade seated in a transverse groove in the casing, the other end ofsaid guide-arm being fitted in and engaged by a socket in said closure,substantially as specified.

2. The combination of a valve-casing havin g a lateral opening, andprovided in its wall opposite said opening with a transverse groove 13,a removable closure fitted in said opening and provided with a roundsocket 15, a valvedisk seated within the casing at one side of saidlateral opening, and having a stem 9 extending axially of the casing toa point midway of the lateral opening, and a guide-arm having a flatblade fitted terminally in the groove 13, arranged transversely in theeasing, and provided at its opposite end with a radially-winged head 14:fitting snugly in the socket of the closure, said guide arm being my ownI have hereto affixed my signature in provided with a centralguide-opening to rethe presence of two Witnesses. ceive the alvestem,and both guide-arm and the valve being removable through said lat-GEORGE FORTI 5 eral opening when the closure is displaced, WVitnesses:

substantially as specified. J. O. ARMSTRONG;

In testimony that; I claim the foregoing as R. E. WETZEL.
